Stiffness Modification of Standard Surfaces

Tips & Tricks

In the “Edit Surface” dialog box, there is a new tab “Modify Stiffness” for the surface types “Standard” and “Without Tension.” Here you can modify the elements of a stiffness matrix by defining factors as in the case of orthotropic surfaces.

Thus, it is not necessary to define orthotropic surfaces in this case. These modifications are considered in load cases as well as load combinations automatically for the calculation of internal forces and deformations, provided they are not deactivated manually.
